EXPLOSION-ENGINE'.

SPECIFICATIO forming' part of Letters Patent No. 740,864, dated Oftober 6, 1903.

Application lerl October 23, 1901. Serial No. 79,644. (No model.)

To @ZZ-whom, t may concern:

Be it known that I, GEORGE FEANQOIS JAU- BERT, a citizen of Switzerland, and a resident of No. 155 Boulevard Malesherbes, Paris, France, have invented a new and useful Improvement in Explosion-Engines, which improvement is fully set forth in the following specification.

This invention refers to improvements in explosion-engines.

By supplying engines with explosive gas (petroleumoil gas, producer-gas, or like gases) by means of superoxygenated air or oxygen in place of Wi th ordinary air a better efficiency is obtained with an equal quantity of combustible material. This efficiency is increased by operating with a closed circuit,

among the advantages that are thereby at-' tained being that I do not foul the local at'- rnosphere where the motoris being operated and that having no escapement to the air I suppress all cause of fires. This is of particular importance, for example, where the engine is used in the vicinity of oil-Wells or dirigible balloons, &c., Where the discharge of the heated products of combustion in the atmosphere might result in damaging coniiagration. Also after purification the escaping gas is not formed solely of nitrogen, but also of appreciable quantities of oxygen and of gaseous carbids, which latter are returned to the cycle to be utilized, and, further, by the employment of the closed cycle I utilize only the purified gas of combustion mixed with a certain quantity of pure oxygen without drawing on the atmospheric air. In mine-pits, for example, such air would be needed for the respiration of workmen.

The invention will be readily understood by reference to the accompanying drawings, wherein a complete system is shown, partly in Figure 1 and the remainder in Fig. 2.l

o is a gas-engine, which draws the combustible gas from a rubber pocket b, into which it is emptied from the conduit c after having traversed a suitable meter. (Not shown.) The regenerated air is drawn from the rubber pocket CZ. After combustion the exhaust-gases escape from the engine a and having passed through a suitable expansionchamber c e are cooled in a worm f, which is surrounded by cold Water. From thence they pass into a'purifierg of the scrubber type (l have employed with success the rotary purifier sold under the name of Standard 7) ,containing an alkaline solution, (caustic soda, potash, or lime,) which absorbs the carbonio acid. The gases then pass to a mixer h, Where they receive an addition of oxygen derived from the generator t', of any appropriate type. The regenerated gases return to the rubber pocket d, from which they are again aspirated by the engine. Between Vthe generator i and the engine,'as Well as between the Worm f and the scrubber g, suitable meters lr. may, if desired, be interposed.

As will be observed, the circuit is entirely closed.

ln a gas-engine, the combination with the exhaust-pipe thereof, a purifier into which the exhaust-pipe leads, of an exit-pipe leading from the purifier'to a mixer having an oxygensupply,and from thence to the inlet of the engine.

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.
